RE: Conical for T/C .54 Caliber Renegade
I would not let the weight of the conical bother you. Its all shot placement. Just don't aim for bone mass.
There is the maxiball, minnie ball (which did not shoot hunting accuracy well for me), 380 grain REAL conicals, 300 grain REAL conicals, powerbelts, Buffalo Bullet Ball-ets, and Bull Shop conicals (which did not shoot well for me with the 1-48 twist). Some of the heavy weights out there that shoot well are the Buffalo Bullet conicals that are 426 grain. I used them one year and hit shoulder bone and about trashed the whole front end of the deer.
Since you shoot a .54 caliber and your shots are under 100 yards, don't forget the roundball. .54 caliber roundball is deadly. I killed a lot of deer with a .54 caliber roundball.
